In nature, notice how the male works to attract the female. Peacocks (ever seen a peahen? Bor-ring!), and cardinals, for example, are endowed with spectacular plumage, the better to bring the ladies flying in from all around.
But in humans, it’s the opposite. Women cleanse, moisturize, mud pack, pluck, mow, shave, scrub, sandblast, and then paint themselves in an attempt to make themselves more attractive. They chant, "We must, we must, we must increase our bust", and do whatever exercise goes along with said chant, trying to make their sweaters fit better. But men are just wash and go, maybe apply a little cologne, and that’s all they have to do! What is up with that?
